Abstract : Astronomic positioning has been accomplished with the same techniques and instruments for several decades. Many innovative techniques have been developed in the past to reduce instrument and observer errors. Now, however, with new technology and electronic miniaturization, the observer can be eliminated along with most of the instrument errors. A vertically oriented telescope, which has a series of slits located in the focal plane, is used to replace the observer. A microminiature fourth generation computer will control all operations and record all data observed. In addition the computer will perform an on-site computation of the astronomic position. An instrument of this type should be able to produce astronomic latitude and longitude to an accuracy of 0.3 arc sec, one sigma. (Author)
